Material Safety Data Sheet-Tertiary Butyl Hydroquinone
Introduction
Tert Butyl HydroquinoneTert Butyl Hydroquinone (TBHQ) is used as an anti-oxidant in stabilising various edible oils and food products. TBHQ prevents rancidity of lard and bitterness of oils. TBHQ is non-toxic in the necessary proportions and is stable at high temperatures, making it an ideal anti-oxidant for deep fried processed foods such as potato chips. Further, the small quantities required make TBHQ a very economical product to use.

Uses and advantages of using TBHQ
Fats and oils are quick to oxidise when in contact with air. Oxidation of fats and oils results in an “off” flavour. Food anti-oxidants such as TBHQ prevent the oxidation of fats and oils and thus increase the shelf of the same.
Fried Foods
High temperature and moisture conditions are observed during frying of foods, resulting in a short shelf life for the fried product. Adding TBHQ during the frying operation results in a longer shelf life for the fried food as TBHQ “carries through” the fried product.
Vegetable Oils
Even though vegetable oils contain natural anti-oxidants they are still susceptible to oxidation. The more unsaturated oils such as soybean and sunflower are particularly prone to oxidation. TBHQ is an excellent anti-oxidant for use in vegetable oils.
Animal Fats
Animal fats do not contain any natural anti-oxidants. Thus, animal fats are prone to oxidation. TBHQ shows excellent anti-oxidation properties in lard and animal fats.
Pastry, Crackers (Biscuits)
TBHQ is added to pastries, crackers/biscuits to extend their shelf life.
Pharmaceutical products such as creams and oils contain fats and oils. TBHQ is added to prevent oxidation of the same.
1.
TBHQ is non-toxic in the required level of concentrations
2.
Addition of TBHQ is easy
3.
Does not give objectionable colour even in contact with metals like Iron and Copper
4.
Reasonable Cost – Since TBHQ is added only in small quantities, the cost of addition is minimal
5.
TBHQ is stable at high temperatures
Usage of TBHQRegulations governing the use of anti-oxidants differ from country to country. However, in India for most edible oils, the concentration of TBHQ should not exceed 0.02% by weight of the fat or oil, including essential oil. Thus, 3 Gms. of TBHQ are added in a 15 Kg or 15 Lt. box of oil.
TBHQ is added to the oil directly by heating the fat or oil to 65°C along with agitation. When the entire body of fat is in motion, the anti-oxidant is added slowly and the agitation is continued for twenty minutes thereafter.

TBHQ is available in convenient packaging of 500 Gms., 1 Kg, 5 Kg , 10Kg and 25 Kgs.
Store TBHQ in cool, dry place in air-tight container.
Note : Users should determine the suitability and appropriateness of TBHQ manufactured by K.K. Poonja & Sons for their products as per local regulations.
